Working largely without credit in the Hollywood system, storyboard artist Harold and film researcher Lillian left an indelible mark on classic films by Alfred Hitchcock, Steven Spielberg, Mel Brooks, Stanley Kubrick, Roman Polanski and many more. Through an engaging mix of love letters, film clips and candid conversations with Harold and Lillian, Danny DeVito, Mel Brooks, Francis Ford Coppola and others, this deeply engaging documentary offers both a moving portrait of a marriage and a celebration of the unknown talents that help shape the films we love.

One of the very best documentaries ever made about movies. - Film Journal international
